PROTECTIVE DEVICE FOR WINDOWS Filed June 5, 1952 Patented Feb. 6, 1934UNITED `STATES .PATENT OFFICE This invention relates to protectiveguards for store windows.

One of the objects of the invention is in the provision of a protectiveguard for store windows which guard may be placed either on the outsideor inside of the window.

Another object lies in the provision of a protective guard for storewindows, the same being operated by the storekeeper in such manner thatthe guard Vprotects either the inside or -outside of the window.

Still another object lies in the provision of a protective guard forstore windows which is carried in a track forming a part of the guardmechlI anism, said track permitting the guard izo-entirely surround thestore windows, irrespective of their shape or angular position.

Yet another object lies in the provision yof a protective guard forstore windows and the like,

said guard having a plurality of intermittently `disposed solid doublelinksand pivotal links, the same being carried in upper and lower trackmembers as to permit ease of movement of the guard, `either from acollapsed to an expanded position or vice versa.

A still further object is `in the provision of a protective guard forstore windows `and the like, the guard itself being collapsible innature and being made up of a plurality of solid and pivotally connectedlinks, said .links having Vtheir upper ends carried in a track in suchmanner that the track forms a part of the vguard mechanism, the trackfurther being provided with means which permits the collapsibility ofthe entire guard in a minimum of space, and with a minimum of effort.

An additional object lies in the provision of a flexible protectiveguard for store windows and the like, the same being capable ofsecurement to the windows in a manner to surround corners or any unusualshaping of the window, said ilexible protective guard being carried in atrack forming a part of the guard, the guard itself comprising a seriesof pivotally connected guard vmembers disposed vertically and carried ina rolling manner within the track so as to permit ease of movement bythe operator or storekeeper, whether upon the inside or outside of thewindow, there being also provided an automatically operating cammechanism in connection with the track which permits collapsibility ofthe guard vin a nonexposed and minimum space.

Before referring specifically to the drawing for a detail description ofapplicants invention, it might be stated that the present applicant hasdevised Aa protective guard of a iiexible and collapsible nature forstore windows of any size or structural arrangement. In other words, byvirtue o-f the disposition of the iiexible kguard and lmanner ofsupporting and carrying same in upper andlower tracks, the guard may beused to surround store windows `either upon the outside or upon theinside. By using a protective guard of this character, the storekeepermay `operate the guard without ldisarranging his display in the Windowand the guard has the improved feature of being readily Aand easilymoved to a guard or to a collapsed position. Further, it will be foundthat by the peculiar larrangement of double welded or solid links inconnection with intermittent pivotal links, the guard is not onlystrengthened to a great degree, but further, when this combination oflinks is operatively connected with the upper and lower tracks, theguard ceases to be a exible and `'collapsible guard unit, but is aprotective mechanism which is supported not only from above and Abelowand at either end, but also between the tracks as well.

view taken on the rIhe device has obviously for its more importantpurpose the protection of store windows, and the same is sufficientlyflexible to be applied to windows, irrespective of their curved orrectangular shape or other form.

In Fig. 7 of the drawing, a sub-combination of elements has been shown,wherein the dual solid links and intermittent pivotal links are carriedin an upper and lower track in a more simple manner for the purpose ofcovering a dat opening or closure member, whether a door or a window.

Applicant again points out the fact that be-V cause of the arrangementof the guard in connection with the track, same may be moved by theoperator with a minimum of effort and when Figs. 4, 5 and 6 are viewed,it is quite apparent that by the special cam arrangement used inconnection with the track, an automatic collapsing of the guard into aminimum of space is effected.

Referring specifically to the rawing, in Fig. 1 is shown in diagrammaticmanner the conventional rectangularly shaped frame of a store window 10.In this figure the store window is shown in various forms and the trackforming a part of applicants guard and designated 11 is shown not only`on the inside of the window but also on the outside. The upper track,which has been designated 11a is similar in every detail to the lowertrack 11. The track itself is adapted to be secured to the structuralportion of the building by means of plural clamps or bracket members 12.Obviously, the manner of attaching the track to the building could beaccomplished in a number of ways without departing in the least from thespirit of the invention.

The tracks 11 and 11a are formed of rectangularly shaped steel portions,the same being apertured in the manner shown at 13.

Referring specifically to Fig. 9, there is found therein a detaildisclosure of the manner of carrying the guard member within the tracks11 and 11a. In other words, certain of the guard links are secured as at14 to dual roller members 15, the same being carried, as shown clearlyin Fig. 9, within the upper track 11a. By hanging the links, or ratherthe protective guards, from an elevated position, it is not necessarythat the lower ends of the links be similarly carried in a roll typemanner, although of course dual rollers might just as well be connectedat the lower end.

It will be noted that the guard itself is made up of a plurality oflinks having different description. In the iirst place, vertical guardmembers 16 and 17 are connected in a fixed or solid manner, as shown inFig. 10 rof the drawing. These links are connected to the dual straps 18and 19 which are welded as: at 20 and 21 to the befofe mentioned links16 and 17.

Referring to Fig. 2, it is found that adjacent guards 16 lie horizontalpivotal connecting straps 22 which connect adjacent dual and solidvertical guard members 23 and 23a with similarly formed and beforementioned duel vertical guard members 16 and 17. Applicant has merelydescribed the upper solid connection and pivotal links although it isquite apparent that this link connection is carried out throughout theentire guard and that the lower connecting mechanism is exactly the sameas shown at the top.

In Fig. 2, it will be noted, however, that additional guard mechanismsuch as the members 24 and 25 have been secured tothe before mentionedvertical guards and link mechanism, merely for additional protection.V.The same are obviously secured to the members 16, 17 and 22 in exactlythe same manner as above described. Applicant might carry out thedescription of the intermittently disposed dual solid links and theadjacent pivotal links, but it is believed that in view of the abovedescription same is quite apparent.

It will be noted that the vertical guard members 16 and 17, and 23 and23a all have their upper and lower ends carried in and protected by thebefore mentioned upper and lower tracks 11 and 11a. A few of these linkshave the roller members 15 attached thereto and act as a means forsupporting the flexible or collapsible guard within the tracks. However,at all times the guard is secured within the tracks and is carriedthereby in such manner that there is a support for the vertical membersnot only at either end but also at the top and bottom. Further, the useof the dual solid links in connection with the pivotal links greatlyassists in strengthening the flexible guard mechanism throughout.

In Fig. 7 of the drawing a modification has been shown of applicantsguard, wherein same is used for covering a flat space. In this instance,the upper and lower tracks 26 and 27 are receiving places Q for thesolidly connected vertical guards 28 and 29, which are. pivoted toadjacent similar portions byl means of the plural pivoted connectinglinks 30.

In Figs. 7 and 8 also has been sho-wn, as previously noted, amodification of applicants collapsible guard, wherein there is not shownexactly similar track mechanism for supporting the guards in a rolledmanner. However, it is noted that the same character lof dual solidguard members are used in combination with the pivoted links.

In Figs. 4, 5 and 6, the manner of collapsing the pivotal dual guardmembers in a minimum of space is believed to be clearly shown. In thesefigures it will be noted that the track is broken in the manner shown at31 and that a guard member 32 is disposed adjacent this track opening. Apivoted cam member is shown at 33, said member being normally held inthe position shown in Fig. 6, wherein a spring 34 abutting one side ofthe cam normally holds the cam in the position shown in this figure. Itwill be noted in Fig. 6 also that the lower ends of the vertical guardmembers will pass the cam 33 when said cam is in the position shown inthis figure. However, as the lower end of the guard continues its normalmovement along the track to a collapsed position, that member strikesthe cam surface 35 in the manner shown clearly in Fig. 5, whereby thethrow-out end 36 of the cam is carried to a position clearly shown inFig. 5 and to such a position as to eject the following guard memberthrough the track opening 31. However, the passage of this guard portionthrough the track opening, il,

taken in connection with the iinal movement of the previous guardelement beyond the cam 33, permits the spring 34 to again depress thecam to the positionshown in Fig. 6, whereupon the following dependingguard member will continue in normal manner along the track, said memberfinally moving the cam to the position previously mentioned in Fig. 5,whereupon the automatic throw-out portion 36 will again eject thefollowing 4guard member through the track opening. Thus,

it is found that the collapsing of the protective guard operatesautomatically first to carry one of the guards along the track andthereupon and automatically to eject the next guard through the trackopening, while'the following guard member iic 'izo

continues its normal travel. Thus, with an automatic operation the guardmembers are collapsed to such a position as to occupy a minimum space,as shown in Figs. 4, 5 and 6 of the drawing.

With respect to the operation of applicants device, itis believed fromthe above description taken in connection with the drawing that it isquite obvious that the guard may be operated either upon the inside orthe outside of a show window of any size, shape or form.

It is believed further to be apparent that the guard is made up of aseries of solid dual vertically disposed guard members connected byintervening pivotal links; that the collapsible guard is carried in aneasy manner in the track by virtue of the roll supports at the top;further, that the use of these dual solid vertical guard members andtheir manner of support in both the upper and lower tracks presents aformidable protective guard. Finally, the collapsing of the guard to aposition where same will occupy a minimum space is believed clearlyunderstood from viewing Figs. 4, 5 and 6 of the drawing, wherein theoperation of the automatic cam activated by the upwardly and downwardlyprojecting ends of the guard members is clearly set forth. The action ofone of the guards controls the direction of movement of the cam at onetime while the following depending or upwardly projecting end of theguard operates in a reverse direction to accomplish the collapsingoperation.

With respect to Figs. '7 and 8 of the drawing, ihe operation of thecollapsible guard when used upon a window in a single plane or across anenclosure such as a door or the like, is believed clearly set forth.`The same character of dual solid vertical guard members with theintervening pivoted links and the manner of collapsibility is believedto clearly disclose the fact that applicants device may be used as aprotective medium without the use of the upper and lower tracks and theroller mounting of the guard therein and the automatically operating camfor collapsing same.

Further, with respect to the manner of securing applicants collapsibleguard to the framing structure surrounding the window, it iscontemplated that at the end of the guard wherein same is capable ofbeing collapsed in a minimum space,

the guard shall be attached securely to the surrounding framework andthat at the oher end to which same is adapted to be extended orexpanded, same shall be connected to the framework by any character oflocking mechanism such as a padlock or the like. As a matter of fact, itis immaterial Whether the guard is secured in a detachable or lockedposition at either end thereof.

What I claim is:

1. A protective device for windows comprising in combination upper andlower track portions, a

series of xedly secured, dual vertical guard members having their upperand lower ends carried in said tracks, intervening pivotal connectionsfor said guard members and mechanism automatically operating inconnection with said track members for automatically collapsing theguard in a minimum of space.

2.
